Elbridge Gerry (1744-1814) was a Democrat. Gerrymandering was first used in Massachussets in 1812 by the Democratic-Republican Governor, Elbridge Gerry to keep the State Senate in his party's control even though Gerry himself lost the 1812 election for governor. The Democratic-Republican party became the Democratic party.
Obviously, after the Democrats showed how effective gerrymandering is, Republicans began using the tactic too.
Since both sides have used gerrymandering for a very long time, it's unlikely that the system will change.
